Answer:
 5 mph, 11 mph
Step-by-step explanation:
Together, they cover 24 miles in 1.5 hours, so their total rate of speed is ...
 (24 mi)/(1.5 h) = 16 mi/h
If s is the rate of the slower jogger, then s+6 is the rate of the faster one. Their total speed is ...
 s + (s+6) = 16
 2s = 10 . . . . . . . subtract 6
 s = 5 . . . . . . . . . divide by 2
 s+6 = 11
The rates of the joggers are 5 mph and 11 mph.
